How do you factorise x2-11x-10?
This does not factor over the field of rational numbers. If does factor over the reals. Use the quadratic formula to find the roots for the related quadratic equation: x2-11x-10 = 0 Cal them r1 and r2. The factors are (x - r1) and (x - r2.)
What word in algebra is used to determine the number of x-intercepts a quadratic has?
These are the real ROOTS of the quadratic equation when it equals zero. Example : x2- 7x + 10 = 0 can be written as (x - 5)(x - 2) = 0 Then x = 5 and x = 2 are the roots of this equation.
When 11 times a certain integer is subtracted from twice the square of the integer the result is 21find the integer?
-10
What are the roots of the quadratic equation for x2 - 12x plus 20 equals 0?
x2-12x+20=0you can factor this equation into:(x-10)(x-2)=0set each factor equal to zero & solve for x to get:x=10 & x=2
What is an example of an easy quadratic equation?
x^2 + 7x + 10

Solve the equation 6x plus 10 equals 11x?
If 6x + 10 = 11x , then x=2.

-30 x-10 plus 11x?
The equation -30 times -10 plus 11X equals -29. This is a math problem.
How do you determine quadratic eqauation given the roots?
If for example the roots where x = 2 or x =5 then within the brackets this would be (x-2)(x-5) = 0 and by multiplying out the brackets the quadratic equation comes to x2-7x+10 = 0
What two numbers when multiplied OR added together equal 10?
5+5 By quadratic equation the two numbers (roots) are: 8.872983346 and 1.127016653 Added together = 10 Multiplied = 10
What is the discriminant in the quadratic equation x2 plus 11x plus 121 equals x plus 96?
The discriminant in the quadratic equation x2 + 11x + 121 = x + 96 is 0.Simplify the equation to the form Ax2 + Bx + C = 0 and you get x2 + 10x + 25 = 0. The discriminant is B2 - 4AC or 100 - (4)(1)(25) or 100 - 100 or 0.Not asked, but answered for completeness - since the discriminant is 0, there is one real solution, namely x = (-10 +/- 00.5) / 2 = -5
When 11 times a certain integer is subtracted from twice the square of the integer the result is 21find the integer?
-10
What are the roots of the quadratic equation for x2 - 12x plus 20 equals 0?
x2-12x+20=0you can factor this equation into:(x-10)(x-2)=0set each factor equal to zero & solve for x to get:x=10 & x=2
What is the solution of the quadratic equation x2 plus 3x-10?
1,2.5
What is an example of an easy quadratic equation?
